PS-Merge: a mixed belief merging operator


When information comes from different sources inconsistent beliefs may appear. To handle inconsistency, several model-based belief merging operators have been proposed. Starting from the beliefs of a group of agents which might conflict, these operators return a unique consistent belief base which represents the beliefs of the group. The operators, parameterized by a distance between interpretations and aggregation function, usually only take into account consistent bases.
Consequently, the information in the base, which is not responsible for conflicts, may be ignored. This paper presents an algorithm for implementing the $PS$-$Merge$ operator, an alternative method of merging that uses the notion of Partial Satisfiability instead of distance measures. This operator allows us to take into account inconsistent bases. Also in order to use the PS-Merge operator to solve ITC problems a pre-processing transformation was proposed.
